Regenerative Resistor
When the operating motor is stopped, the motor works like the
generator, which produces energy, regenerative energy.
The servo drive absorbs to some extent the regenerative energy
produced while the motor stops. But if the amount of the regenerative
energy exceeds the existing capacity, an additional device to consume
the energy is required. If excessive regenerative energy overstrains the
servo drive, it can cause damage to the system. To prevent this, the
servo drive has its own internal protective circuit.
Regenerative Resistor
Regenerative energy is produced in the following cases.
•
During deceleration.
•
When the force of the load revolves the motor continuously. For instance,
minus load condition or when the vertical load is operated.
Under the condition of minus load where load revolves servo motor
with gravity and vertical load where continuing regenerative energy
occurs excessively, excessive regenerative energy can occur. If
regenerative energy is consumed, however, internal regenerative
resistor is available without any measures.
